My PC storage is disappearing for no reason

Since yesterday, I’ve been dealing with this weird issue where my hard drive space just keeps vanishing—I mean, literally disappearing while I'm browsing the web. Every time I hop online, I lose about 300 MB of storage, even though I haven't downloaded a single thing. I wasn't even watching videos or anything; I was just hanging out on sites like Reddit.

The thing is, since I'm down to my last 10 GB of free space, my whole computer is starting to crawl, and some websites won't even load because I'm hitting "low disk space" errors, lol!

I already tried running an antivirus scan, but it didn't flag a single thing, so I'm feeling a bit stumped. Does anyone here have any idea what might be causing this or how I can fix it? 🤔

The issue seems to be that you’ve got some junk running in the background that starts downloading things the second you jump online. I’d suggest running a full scan on your computer using Malwarebytes and then follow it up with AdwCleaner just to be safe.

Go ahead and disable System Restore.
